Carla's plant was 10 2/3 inches tall. Yolanda's was 8 3/4 inches tall. How much taller was Carla's plant than Yolanda's?

1 answer:

6 0

It is easy to subtract fractions by converting them into decimals first. To convert is numerator divided by denominator. So, 10 1/2 would be 10.5 and 8 3/4 would be 8. 75. Now, you can subtract them. Start at the hundredth place so subtract 5 from 0 ( because 10.5 can also be 10.50) so it would be 5. Next, 5 -7 ( so you borrow 1 from 10 so 5 would become 15 and 10 is 9) is 7. Last, subtract your whole number. 9 - 8 = 1. So, your answer would be 1. 75. To convert it to fraction, you need to write it as 1 75/ 100 and simplify it which is 1 3/4. So, Carla's plant is 1 3/4 inches taller than Yolanda's plant Hope it helps!!!!

Answer:

(a) 720 ways

(b) 120 ways

Step-by-step explanation:

Given

$Word = DANCER$

$n =6$ --- number of letters

Solving (a): Number of arrangements.

We have:

$n =6$

So, the number of arrangements is calculated as:

$Total =n!$

This gives:

$Total =6!$

This gives:

$Total =6*5*4*3*2*1$

$Total =720$

Solving (b): DA as a unit

DA as a unit implies that, we have:

[DA] N C E R

So, we have:

$n = 5$

So, the number of arrangements is calculated as:

$Total =n!$

This gives:

$Total =5!$

This gives:

$Total =5*4*3*2*1$

$Total =120$

Solving (c): NCE as a unit

NCE as a unit implies that, we have:

D A [NCE] R

So, we have:

$n = 4$

So, the number of arrangements is calculated as:

$Total =n!$

This gives:

$Total =4!$

This gives:

$Total =4*3*2*1$

$Total =24$

Q # 13. please help to solve this

True [87]

To solve this problem you must apply the fomrula for calculate the area of a cylinder, which is shown below:
A=2πrh+2πr^2
Where r is the radius and h is the height of the cylinder
You have that r=15.1 inches and h=12.8 inches, then:
A=2πrh+2r^2
A=2π(15.1 in)(12.8 in)+2π(15.1 in)^2
A=2647 in^2
The answer is 2647 in^2
